Every Guidelines Ruler comes with an Angle Line Marker

Pins underneath the Marker fit into holes around the 30º, 45º and 60º numbers in the center of each angle line on the ruler.

Angle Lines run in both directions on the Ruler. Once you know the angle you want to cut and which way you want to cut it, you can mark the line, so you'll cut the right angle the right way every time.

For example, to make 60º diamonds, you can mark the 60º angle line in either direction, making it easy for right or left handers to cut in whichever way works best for them.

How to Make 45º Diamonds

First, set the Fabric Guide to the size you want the diamond to finish at, plus 1/2" for seam allowance, and cut a strip. Then line the edge of the strip along the angle line you marked and cut that angle on the end of your strip.

Rotate the strip and with the Fabric Guide still set on the same line you used to cut the strip, line the angled end of the strip you just cut, up to the Guide, and start cutting diamonds.
